Description

Technical Field

[0001] This utility model relates to the technical field of pylorus detection devices, specifically a pylorus detection device based on color recognition. Background Technology

[0002] Most people are familiar with Helicobacter pylori, a bacterium that is not only a major cause of gastritis and peptic ulcers but also a high-risk factor for stomach cancer. Statistics show that the current infection rate in my country is approximately 50%, and the infection rate is increasing among people aged 20-50, reaching as high as 69% in those over 50. Among infected individuals, about 15% to 20% develop peptic ulcers, 5% to 10% develop indigestion, and about 1% develop gastric malignancies.

[0003] Using Helicobacter pylori urease test strips allows for convenient and low-cost home screening for Helicobacter pylori, which can be performed simultaneously with gastroscopy. A search revealed a utility model patent with authorization publication number CN116068170B, which discloses a test strip and kit for detecting Helicobacter pylori. The test strip includes a test line prepared from a monoclonal antibody for detecting Helicobacter pylori. This monoclonal antibody is prepared using an antigen as an immunogen, as shown in SEQ ID NO.1, and the monoclonal antibodies prepared from this antigen all exhibit high specificity.

[0004] However, these test strips rely on visual observation of color changes to determine the results, which is highly subjective and prone to inaccurate judgment. Utility Model Content

[0005] The purpose of this invention is to provide a color-recognition-based pylorus detection device, which solves the problem that existing pylorus test strips are prone to inaccurate judgments due to their strong subjective judgment.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a pylorus detection device based on color recognition, comprising a housing, a circuit board mounted inside the housing by bolts, a microcontroller and an LCD display screen mounted on the circuit board, a light path insert mounted on the upper right side of the circuit board by bolts, a test paper pen inserted into the inner side of the light path insert, a light path protrusion structure provided on the lower edge of the test paper pen, a light path detection switch provided on the circuit board, and the light path detection switch abutting against the light path protrusion structure.

[0007] Preferably, the inner bottom of the housing is integrally formed with multiple pads, and the pads abut against the circuit board. The pads provide auxiliary support for the circuit board.

[0008] Preferably, the optical path housing is a rectangular frame and made of plastic. One end of the rectangular frame optical path housing has a notch to facilitate the insertion of the test paper pen.

[0009] Preferably, the circuit board is equipped with LED beads and a color sensor, and the bottom of the test strip pen has a test strip color development area, the position of which corresponds to the LED beads and the color sensor. The light emitted by the LED beads on the circuit board shines directly onto the test strip color development area of ​​the light path housing, and then the reflected light is reflected to the color sensor through the test strip color development area. The purpose is to reflect the color of the test strip to the color sensor through the light path.

[0010] Preferably, a transparent glass window is embedded in the outer casing, and the position of the transparent glass window corresponds to the LCD display screen. The transparent glass window facilitates observation of the display status of the LCD display screen from the outside of the outer casing.

[0011] Preferably, a main switch is provided on the housing, and the main switch is electrically connected to the circuit board. The main switch can control the start and stop of the entire machine.

[0012] Preferably, the outer casing has an insertion arrow mark, and the position of the insertion arrow mark corresponds to that of the test paper pen. The insertion arrow mark provides assistance in determining the insertion position of the test paper pen.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This invention involves inserting a paper and pen into the optical path housing. When the optical path switch is pressed, the circuit is powered on. After the test strip completes its test, the white light emitted by the LED beads shines directly onto the center area of ​​the test strip. Through diffuse reflection, the light carrying the color of the test strip is irradiated onto the color sensor. After receiving different colors of light, the color sensor converts the light signal into an electrical signal. By detecting the amount of red, green, and blue light in the reflected light, the sensor compares the results and outputs the detected RGBW value, which is then directly displayed on the LCD screen. This avoids errors caused by subjective judgment. Attached Figure Description

A microcontroller 3 and an LCD display 4 are mounted on the circuit board 2. Multiple pads 101 are integrally formed on the bottom inner side of the housing 1, and these pads 101 abut against the circuit board 2. The pads 101 provide auxiliary support for the circuit board 2. A light path insert 5 is bolted to the upper right side of the circuit board 2. A test paper pen 6 is inserted into the inner side of the light path insert 5. The light path insert 5 is a U-shaped frame made of plastic. One end of the U-shaped light path insert 5 has a notch to facilitate the insertion of the test paper pen 6. The lower edge of the test paper pen 6 has a light path protrusion structure 61. A light path detection switch 7 is mounted on the circuit board 2, and the light path detection switch 7 abuts against the light path protrusion structure 61.

[0022] Please see Figure 4 The circuit board 2 is equipped with LED beads 9 and a color sensor 10. The bottom of the test strip pen 6 is equipped with a test strip color development area 62, and the position of the test strip color development area 62 corresponds to the LED beads 9 and the color sensor 10. The light emitted by the LED beads 9 on the circuit board 2 shines directly onto the test strip color development area 62 of the light path insert 5, and then the reflected light is reflected by the test strip color development area 62 to the color sensor 10. The purpose is to reflect the color of the test strip to the color sensor 10 through the light path.

[0023] Please see Figure 1A transparent glass window 12 is embedded in the outer casing 1, and the position of the transparent glass window 12 corresponds to the LCD display screen 4.

A main switch 8 is provided on the outer casing 1, and the main switch 8 is electrically connected to the circuit board 2. The main switch 8 can control the opening and closing of the entire device. An insertion arrow mark 11 is provided on the outer casing 1, and the position of the insertion arrow mark 11 corresponds to the test paper pen 6.

[0024] The specific implementation process of this utility model is as follows: In use, after pressing the main switch 8, the entire machine is powered on and the LCD display 4 lights up. Then, the sample is applied to the reaction area of ​​the test strip pen 6, and the test strip pen 6 is inserted into the optical path housing 5 inside the instrument, following the arrow 11. After a few minutes, the test result is displayed on the LCD display 4. Furthermore, when the test strip pen 6 with the sample applied is inserted into the device, the optical path protrusion 61 on the test strip pen 6 abuts against the optical path detection switch 7, thereby activating the detection optical path and starting the timer. After a few minutes, the test strip color development is complete, and the light emitted by the LED beads 9 on the circuit board 2 shines directly onto the test strip color development area of ​​the optical path housing 5. 62. The reflected light is then reflected to the color sensor 10 through the color development area 62 of the test strip. The purpose is to reflect the color of the test strip to the color sensor 10 through the light path. The color sensor 10 transmits the identified RGBW value to the IO port of the microcontroller 3. The microcontroller 3 then calculates the RGBW value and determines the test result. Finally, the test result is transmitted to the LCD display 4. Users can view the test result through the LCD display 4, avoiding the result error caused by subjective judgment. It can be used for quick home testing. Moreover, the disposable device can meet the needs of multiple people in the family for testing and can also be used as a preliminary screening for Helicobacter pylori, saving costs and providing strong privacy.
